我在我的RecyclerView的onBindViewHolder方法中使用此逻辑实现了无限滚动类型。适配器类。

    if (position == mItems.size() - 1 && mCurrentPage <= mTotalPageCount) {
        if (mCurrentPage == mTotalPageCount) {
            mLoadImagesListener.noMorePages();
        } else {
            int newPage = mCurrentPage + 1;
            mLoadImagesListener.loadPage(newPage);
        }
    }

使用这段代码，当RecyclerView到达最后一项时，它会增加当前页面和接口上的回调，该接口负责从api加载更多数据并将新结果添加到适配器。

我可以张贴更完整的例子，如果这不是很清楚?

有一个方法public void setOnScrollListener (RecyclerView。OnScrollListener监听器)在https://developer.android.com/reference/android/support/v7/widget/RecyclerView.html#setOnScrollListener%28android.support.v7.widget.RecyclerView.OnScrollListener%29。使用这个

编辑:

在onScrollListener中重写onScrollStateChanged方法并执行此操作

            boolean loadMore = firstVisibleItem + visibleItemCount >= totalItemCount;

            //loading is used to see if its already loading, you have to manually manipulate this boolean variable
            if (loadMore && !loading) {
                 //end of list reached
            }

我刚试了一下:

    final LinearLayoutManager rvLayoutManager = new LinearLayoutManager(this);
    rvMovieList = (RecyclerView) findViewById(R.id.rvMovieList);
    rvMovieList.setLayoutManager(rvLayoutManager);
    adapter = new MovieRecyclerAdapter(this, movies);
    rvMovieList.setAdapter(adapter);
    adapter.notifyDataSetChanged();

    rvMovieList.addOnScrollListener(new OnScrollListener() {
        boolean loading = true;
        int pastVisiblesItems, visibleItemCount, totalItemCount;
        @Override
        public void onScrolled(RecyclerView recyclerView, int dx, int dy) {
            super.onScrolled(recyclerView, dx, dy);

            visibleItemCount = rvLayoutManager.getChildCount();
            totalItemCount = rvLayoutManager.getItemCount();
            pastVisiblesItems = rvLayoutManager.findFirstVisibleItemPosition();

            int lastitem = visibleItemCount + pastVisiblesItems;

            if ( lastitem == totalItemCount
                    && page < total_pages
                    && !keyword.equals("") ) {
                // hit bottom ..

                String strnext;
                if (page == total_pages - 1) {
                    int last = total_results - (page * 20);
                    strnext = String.format(getResources().getString(R.string.next), last);
                } else {
                    strnext = String.format(getResources().getString(R.string.next), 20);
                }
                btNext.setText(strnext);
                btNext.setVisibility(View.VISIBLE);
            } else {
                btNext.setVisibility(View.INVISIBLE);
            }

            if(pastVisiblesItems == 0 &&  page > 1){
                // hit top
                btPrev.setVisibility(View.VISIBLE);
            } else {
                btPrev.setVisibility(View.INVISIBLE);
            }
        }
    });

我搞不清楚在哪里加载真或假，所以我试图删除它，这段代码工作如我所料。

为什么不使用这个逻辑呢?

public void onScrolled(RecyclerView recyclerView, int dx, int dy) {
    int totalItemCount, lastVisibleItemPosition;

    if (dy > 0) {
      totalItemCount = _layoutManager.getItemCount();
      lastVisibleItemPosition = _layoutManager.findLastVisibleItemPosition();

      if (!_isLastItem) {
        if ((totalItemCount - 1) == lastVisibleItemPosition) {
          LogUtil.e("end_of_list");

          _isLastItem = true;
        }
      }
    }
  }

我使用了recyclerview。adapter的onBindViewHolder方法。

适配器:

public interface OnViewHolderListener {
    void onRequestedLastItem();
}

@Override
public void onBindViewHolder(ViewHolder holder, int position) {

    ...

    if (position == getItemCount() - 1) onViewHolderListener.onRequestedLastItem();
}

片段(或活动):

@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
    contentView = inflater.inflate(R.layout.comments_list, container, false);
    recyclerView = (RecyclerView) mContentView.findViewById(R.id.my_recycler_view);
    adapter = new Adapter();
    recyclerView.setAdapter(adapter);

    ...

    adapter.setOnViewHolderListener(new Adapter.OnViewHolderListener() {
        @Override
        public void onRequestedLastItem() {
            //TODO fetch new data from webservice
        }
    });
    return contentView;
}
